Profound Yin Cave Heaven is located in the southeastern part of the Southern Border Cultivation World and is shrouded in Yin Qi all year round. It harbors a large number of Ghost Creatures and also grows a plethora of materials with Yin attributes, attracting a great number of cultivators to hunt there. Most of these cultivators died within Profound Yin Cave Heaven, with only a lucky few surviving to make it out.
A blue Escape Light appeared in the distant sky, swiftly flying towards this place.
Two breaths later, the blue Escape Light stopped, revealing a flying boat shimmering with blue light. Shen Long and Lin Yutong stood on it, their expressions solemn.
"This is Profound Yin Cave Heaven! No wonder there are so many Ghost Creatures with such dense Yin Qi."
Lin Yutong's voice was heavy.
Following Lin Yutong's gaze, one could see a massive black hole with gusts of Yin Wind blowing intermittently, where the sounds of ghosts wailing and wolves howling could be clearly heard.
